SS 430 Flanges

The SS 430 Flange is a critical forging component used to connect pipe sections, valves, pumps, and other equipment, creating a rigid and easily detachable joint. Manufactured from Ferritic Grade 430 Stainless Steel (UNS S43000), these flanges are chosen for their good general corrosion resistance in atmospheric environments and their excellent resistance to oxidation at elevated temperatures. Unlike austenitic stainless steels, Grade 430 is magnetic. Common types include Weld Neck Flanges, Slip-On Flanges, and Blind Flanges . Zeron Fasteners produces these components using advanced forging techniques, ensuring the dense material structure and excellent grain flow necessary to withstand moderate pressure and thermal cycling. SS 430 Flanges are highly reliable in demanding environments such as exhaust systems, furnace parts, and general plant utilities where heat resistance and a cost-effective stainless solution are paramount.
